Electron beam stability is very important for third-generation light sources, especially for the Shanghai Synchrotron Radiation Facility (SSRF), whose ground vibration is much larger than other light sources. The mechanical stability of the magnet girder assemblies (MGAs) in a storage ring is essential for electron beam stability and performance. In order(More)
Storage ring magnets support stability is essential to beam stability. In SSRF, a high stiff girder and unique ball-bearing plus wedge block adjuster were designed. A girder-magnet assembly prototype was assembled, and extensive tests were carried out on the girder-magnet assembly. The results show that its lowest eigenfrequency is 19.5Hz under three points(More)
